You can configure sudoto require a password only every so many minutes. The default is 5 minutes. Read the sudoersman page and scroll down to this:
您可以配置sudo为每隔几分钟就要求输入密码。默认值为 5 分钟。阅读sudoers手册页并向下滚动到：
timestamp_timeout
Number of minutes that can elapse before sudo will ask
for a passwd again. The timeout may include a
fractional component if minute granularity is
insufficient, for example 2.5. The default is 5. Set
this to 0 to always prompt for a password. If set to a
value less than 0 the user's timestamp will never
expire. This can be used to allow users to create or
delete their own timestamps via sudo -v and sudo -k
respectively.

You can pipe the echo'd password into a command. Try something like this:
您可以将 echo 的密码通过管道传输到命令中。尝试这样的事情：
echo myPassword | sudo -S
You can see come more info on this here.
你可以在这里看到更多信息。
Question is, do you REALLY want your password in a shell script file? (just emphasizing that its a terrible idea)
问题是，您真的希望在 shell 脚本文件中输入密码吗？（只是强调这是一个可怕的想法）

Is there a reason that you can't sudo su -to just become the root user instead of prepending all of your commands with sudo blah?
是否有理由让您不能sudo su -成为 root 用户而不是在所有命令前加上sudo blah？

just change ownership of the script to root & set SUID-Bit in user the permissions
只需将脚本的所有权更改为 root 并在用户中设置 SUID-Bit 权限
chmod u=rws g+x o+x script123
chmod u=rws g+x o+x script123
the script will run as root for every user
该脚本将以 root 身份为每个用户运行
